Rounded Rectangle Tool: Click and drag to draw a rounded rectangle of any size. To draw a rounded square, hold down the shift key while you draw the shape. In the rounded rectangle's Properties Box, you can change its color (black is default), choose to show the rounded rectangle's border only (default is to draw filled shapes), change the radius of curvature of the rounded corners, or lock the position of the rounded rectangle.

Placing a rounded rectangle on top of another object connects the rounded rectangle to that object.
